A TTORNE Y cutting the coverings Patented Jan. 17, 1933 ALFRED BURKE, OFNEW YORK,

- This invention relates to lampshades and more particularly to shadeshaving coverings of parchment paper or the like. Among the objects ofthe invention is to provide a shade of attractive appearance which maybe inexpensively manufactured and assembled in large quantities at avery low cost in both labor and material. The paper coverings of shadesof this character are generally made wider or of larger diameter at thebottom thanv at the top. As at present manufactured, considerable wastematerial is produced in from'sheets of stock. My invention contemplatesthe provision of a covering of such form and construction that it may becut from a strip or sheet of paper without any material waste.

Furthermore, in the ordinary lamp shade of this type the covering isusually supported on a wire frame and is held thereon by lacing thecovering with a cord around the frame or by fastening it to the framewith strips of gummed paper. According to this invention I provide alamp shade construction wherein the customary frame is dispensed with,and in which the covering is 'provided with locking means whereby it maybe readily and securely fastened to a supporting ring. Other objectsand-advantages of the invention will appear from the followingdescription thereof, reference bein had to the accompanying drawing, inwhic Figure. 1 is a perspective view of one form of lamp shade embodyingmy invention;

Referring to the drawing, 10 indicates the covering member of the shade,which covering member is made of a fiat strip of parchment paper or likematerial having parallel upper and lower edges 11 and 1-2 and of such ofthe lamp shade form that a plurality of. the covering may 1532. SerialNo. 626,275

be successively cut from a sheet or strip of paper of suitable widthwithout any material waste. As usually made, the coverings of shades ofthis character have curved upper and lower edges'of difierent curvature,the lower edge being considerably longer than the upper edge. The formof the coverings heretofore used is wasteful of material in cutting anddoes not permit of as many coverings being but from a strip or sheet ofa given size as do my improved coveringsr To provide coverings which intheir. completed shape will be smaller in diameter at the top than atthe bottom, I form the paper strip 10 with a series of scorings disposedat intervals'along its length as shown in Fig. 5. Each scoringpreferably consists of a central vertical score 13 and a pair ofdownwardly converging scores 14. The paper strip thus scored issubsequently bent to form a series of inwardly extending upright folds15 which folds are deeper at their tops -than at their bottoms, thusforming a shade which in its completed form is wider or of greaterdiameter at the bottom than at the top.

It will be observed that the paper strip 10, in between each pair ofscores 14 and adjacent its upper edge, is provided with a pair ofoppositely disposed holes 16-16 which holes are connected together bymeans of a pair of downwardly converging slits 17 said slits meeting atthe central vertical score 13 and afi'ording entrance to the holes forthe purpose hereafter described.

18 is a wire 'ringupon which the covering issupported. The ring isprovided'with spi- N. Y., ASSIGNOR TO THE PARCHLITE CORPORATION, I

der arms 19 which carry a suitable fixture for attaching the shade to alamp. In the present:

instance this fixture comprises a pair of spring clips or loops 20adapted to clam overthe bulb or globe of an electric lamp. n fasteningthe covering 10 to the ring 18, as illustrated in Fig. 3 of the drawing,the slits 17 of each fold 15 are in turn hooked over the 'ring so thatthe ring engages in and'passes through each pair of holes 16. Thisprovides a very rapid and easy method of attaching the covering to theringwithoutthe necessity of lacing or otherwise fastening the coveringin place. After the covering has been placed on the ring, the meetingmarginal edges 21 and 22 of the covering are fastened together by meansof rivets or eyelets 23, as shown in Fig. 4, or in any other desiredmanner.

The slits 17 formdownwardly extending hook-like portions 24 in the bodyof the covering 10. When the covering is placed on the ring theseportions 24 hook over the ring and prevent any accidental displacementof the covering laterally of the ring, it being understood that when thecovering is applied to the ring the edges of the slits 17 springtogether and thus these slits, together with the hook-like portions 24,constitute means for effectually locking the covering in place onthering.

It is to be noted that my improved lamp shade has only a singlesupporting ring at its top and does not embody a complete frame as isusual in lamp shades of this character.

Various modifications in the details of the construction herein shownand described may be made without departing from the spirit or scope ofmy invention.

What I claim is 1. A lamp shade comprising a supporting ring, a papercovering having substantially parallel upper and lower edges, saidcovering having inwardly extending folds at intervals around itsperiphery, said folds being deeper at their tops than at their bottomsand tapering lengthwise, oppositely disposed holes in the walls of thefolds near their tops through which holes the supporting ring passes,slits converging from the holes and meeting at the inner edges of thefolds to permit of inserting the ring into the holes, said slits forminghook-like port-ions in the body of the covering strip which hook-likeportions extend inwardly over the supporting ring and lock the coveringon the ring against lateral displacement.

2. A lamp shade comprising a supporting ring. a paper covering havinginwardly extending folds at intervals around its periphery, said foldsbeing deeper at their tops than at their bottoms and taperinglengthwise, oppositely disposed holes in the walls of the folds neartheir tops through which .holes the supporting ring passes, slits c0n-'verging from the holes and meeting at the inner edges of the folds topermit of inserting the ring into the holes, said'slits forminghook-like portions in the body of the covering strip which hook-likeportions extend inwardly over the supporting ring and lock the coveringon the ring against lateral displacement.

3. A lamp shade comprising a supporting ring, a paper covering havinginwardly extending folds at intervals around its periphery, said foldsbeing deeper at their tops than at their bottoms, oppositely disposedholes in the walls of the folds near their tops, through which holes thesupporting ring passes, and slits converging downwardly from the holesand meeting at the inner edges of the folds to permit of inserting thering into the holes.

4. A lamp shade comprising a supporting ring, a paper covering havinginwardly extending folds at intervals around its periphery, oppositelydisposedholes in the walls of the folds near their tops, through whichholes the supporting ring passes, and slits converging downwardly fromthe holes and meeting at the inner edges of the folds to permit ofinserting the ring into the holes.

5. A lamp shade comprising a supporting ring, a paper covering havinginwardly extending folds at intervals around its periphery, oppositelydisposed holes in the walls of the folds near their tops through whichholes the supporting ring passes, and slits connecting said holes topermit of inserting the ring into the holes.
